The Webley and Scott did have an L shaped extension that I think might have interacted with the lever to lock or act as third fastener. The lugs were smaller as was the action bar...I have now moved on.

I asked about a Greener Empire but they also said R15,000. Bit much for a gun to be later cut up.

They had a Stevens 311. I thought about it since the first goal is to just get a gun in the House.
